Large-span buildings, usually, refers to those buildings with a span of more than 60 meters. This kind of building is very characteristic in appearance. It is generally more common in various theaters, exhibition halls and other public buildings. It is also used in industrial plants. Gymnasium is a large-span building, its own shape, function, purpose, use Factors such as conditions determine that its structural scheme can adopt beam type, frame type, spherical grid to And suspension - suspension cable and other internal and external modeling; The building of the gymnasium is made of high-strength steel, and the shape and structure are generally very individual. During the construction, attention should be paid to the construction problems of the roof truss, suspended ceiling and other building parts. Therefore, in the construction of the gymnasium, when installing the temporary support system of the steel structure, the method of erecting full-scale scaffolding is often used. As a means of support, the lightning frame not only satisfies the function of the gymnasium, but also lays a solid foundation for the subsequent installation of steel components and prestressed construction, which effectively solves the problem of using the full-scale scaffolding method to a large extent.
